Melissa, Thank you very much for your detailed instructions. I'm sure that will be a huge help when we start on our next board. The only question I have left is whether you prefer a hot air or infrared preheater. It looks like Hakko makes both type

The high thermal mass of metal core boards makes them difficult to heat with hot air convection heating or IR. So, edge heaters are used for effective heating of heavy core circuit boards. Hakko and VJ Electronix offer edge heaters. We imagine othe

If you extend the pads you get the effect that the solder below the component is pushed to the outside land which results in a very low standoff of the component, deteriorate the overall quality of the solder joint. Hot air (pencil or some of the sem

Hi! I have been studying the reflow process. And now, I am researching for a recommended reflow oven that can process a small to low-medium production SMT soldering. For the experts in the reflow field, please recommend a reliable reflow oven. Here

As was stated, there are a number of variables that could come into play. I have used AirVac DRS26 and SRT Machines. We are now using Shuttle Star which has IR as well as hot air heat. This works much better for us. You can view these at. http://www.

The best test will be to X-ray BGA under 3-D X-ray. About the techniques used for BGA repair you can probably take closer look to some BGA repair stations, even though I have seen it done with hot air gun in the early days.

Thank you for the great feedback. We're definitely taking all of these into consideration. Currently, we're shooting for the following: - JTAG Testing setup - Rework station - A hot air rework station - A quality microscope/vision system Have

I have a problem with some particle, dust and solder paste contaminate on PCB rack and need to clean up once a week by manual. Now looking for the equipment to do Inline cleaning with water jet & Hot air Dry concept. Not too big machine and concept l

Yes, the barycenter causes drop off since only leads at one side, so a variation of re-flow oven, such as vibration or hot air flow, low re-flow time could help a little. So, how you solve this issue after many months?

I forgot to update this. Customer insisted on reflowing SIM card directly to PCB, as per their previous CEM. It worked. No deformation of the SIM card - assembly works - records data to SIM card. Note that using hot air reflow type (rework station)d
